We could boot Gest OS with 64 bit of CentS 6 on Vmware ESXi 5.5

I am  mori_yui

We developed ESXi 5.50 and converted Gest OS on VmPlaer with VMware vCenter Converter Standalone Client.

Gest OS is normally converted to ESXi 5.5 and recognized.

However we boot Gest OS on ESXi and the following error message is displayed on Gest OS.

"This kernel requires an x86-64 CPU, but only detected an i686 CPU.

Unable to boot - please use a kernel appropriate for your CPU."  appears to Gest OS when it boots.

We could not go more forward with it and boot Gest OS.

In this case how should we resolve this issue?

For your information we write the Spec of Host OS and Gest OS below.

I guess the CPU spec(CPU Intel(R) Pentium(R))  is not compatible with with ESXi 5.5 on Host OS.

I ' not sure about the details of cause.

It is all right if we downgrade ESX 5.5 to deal with this issue.

The Pentium E2160 CPU is not in the list of CPUs of the VMware Compatibility Guide. It also does not have Intel Virtualization Technology (VT-x) feature.

Without VT-x, this Pentium E2160 cannot run any 64-bit OS guest VM (not just CentOS 6.6).

You should look for a machine with a CPU that at least have the VT-x feature (Intel chips) or SVM (for AMD). For more advanced use cases and better VM performance, the CPU should have SLAT capability (in Intel it is called EPT while AMD it is called RVI). For Intel CPU, it is best to use something that is from Westmere family (2010) and later.

Use the VMware compatibility guide as reference for supported CPUs, network cards, I/O, etc for specific ESXi versions.
